Ukrainian filmmaker Oleg Sentsov and activist Sasha Kolchenko were both detained in occupied Crimea on May 10, 2014. They were accused of plotting terrorist acts, taken to Russia and convicted. Kolchenko was sentenced to 10 years in prison and Sentsov – 20.

Sentsov and Kolchenko were first held in a detention center in Moscow, tried in Rostov, transported to the Urals and then to the Russian Arctic. Between the two of them, they have covered almost 20,000 kilometers, or, half the distance around the Earth. Their entire journey has been within Russia. Or actually, within its prison system.

We traveled to the key sites along their transport route – where the Ukrainian consuls were denied access and where lawyers today face difficulties getting in – to find out in what conditions they are being kept and who is responsible for their fate.
